Dear Colleagues,
Mayara, a student from IFSC currently doing an internship at ISEP, is trying to characterise all possible errors, done in VISIR, while experimenting a very simple 1:1 circuit in AC mode, i.e. one signal generator connected to a single resistor (R) / inductor (L) / or capacitor (C).
Right now, she has been able to characterise the errors with R and C. However, she has not been able to fully characterise the situation with an inductor, basically because she has not found any VISIR node able to measure L, even though the new VISIR nodes, installed in Brazil and Argentina, are equipped with the NI PXI-4072 6 1/2 Digit FlexDMM & LCR meter, which supports this possibility.
The question is: does any partner implemented an interface (DMM or Virtual Instrument – VI) where users may read L (inductances)?
Yours,
Gustavo

Voce tem pressa nesta implementação? Podemos tentar aqui em Florianópolis.
Implementamos novas funcionalidades em um multímetro para que ele ficassem igual aos que usamos em bancada. Assim, acredito que conseguiremos implementar a medida de indutor
Atenciosamente

Olá Luis,
That would be wonderful.
Actually, the original VISIR interface (developed in Flash) has a multimeter interface that includes the L read button (see attached image). However, in our case (VISIR@ISEP node 1), the PXI multimeter does not support L readings (its an older version).
To put it simply: software is ok, hardware is not ok. In the case of VISIR@IFSC hardware is ok, software (i.e. instrument panel) requires development.
Do you think it would be possible to have this, say in one month?
Cheers, Gustavo
Gustavo
Todas as terças tenho uma reunião com os bolsistas do projeto de pretende a expansão e a customização do VISIR no IFSC. Assim, amanhã, levarei esta demanda.
Grande abraço
